  • Patent number: 9676793
    Abstract: Co-crystals of Formula I compounds and their pharmaceutical compositions are novel therapeutics for the treatment of diseases, such as human immunodeficiency virus (HIV) infection, hepatitis B virus (HBV) infection, hepatitis C virus (HCV) infection and cancer. The co-crystal are more stable to oxidation and aqueous degradation, have a better pharmacokinetic profile and superior biological activity than the corresponding tosylate salt form of Formula I compound.

  • Patent number: 9656549
    Abstract: An equalizing unit of a drive train of a motor vehicle includes a clutch device to be oiled in driving mode. In order to stop drag torques which act on the clutch device from the outside, and result in increased dissipation when said clutch device is not required due to an operating state, measures are provided which promote the dry running of the clutch device. The measures include the spatial-functional separation of the oil delivery device from the clutch device and the provision of a braking or decoupling device by which the oil delivery device can be deactivated if there is no oil requirement.

  • Publication number: 20130324709
    Abstract: An improved process for the preparation of (2?R)-2?-deoxy-2?-fluoro-2?-methylcytidine derivatives of formula I wherein R1 is selected from C1-4-alkyl is described. The (2?R)-2?-deoxy-2?-fluoro-2?-methylcytidine derivatives of formula I have the potential to be useful as prodrugs for potent inhibitors of the Hepatitis C Virus (HCV) NS5B polymerase.

  • Publication number: 20070207068
    Abstract: A method for the treatment of catalysts or catalyst carriers by: a) introducing and distributing a gas in the lower section of a reactor containing a catalyst or catalyst carrier bulk material; b) forming a fluidized bed in the reactor; c) treating the particles in the fluidized bed while removing the fine particles an/or retaining the course particles by means of a separating organ and d) discharging the reactor.

  • Publication number: 20030011346
    Abstract: A circuit arrangement comprises a chain (1) composed of double layer capacitors (2). Modules (3) whose impedance lowers when the voltage across one of the double layer capacitors (2) exceeds a prescribed value are connected parallel to the double layer capacitors (2). As a result thereof, over-voltages at the double layer capacitors (2) are effectively suppressed.
